Just as an aside, I recently had my first play around with an external BB, when the one on the bike I borrowed ground to a halt after some particularly muddy riding. It was easy enough to just knock the old sealed bearings out and get some new ones off eBay for about £2 a set. Bashed those in and it runs very nicely now. Not sure how long it'll last, but it was certainly a cheap and easy way of getting it back up to speed!

Pinch bolts on the LH crank.

have you cross checked the bearing code for cheap ones in ebay?


Hope bearings are custom made and the size isn't freely available - the inner diameter is 1mm smaller as you don't use a tophat with them.
